assignors to E-Z-Por Corporation, Chicago, 111., a corporation ofFlorida Filed Dec. 18, 1963, Ser. No. 331,510 4 Claims. (Cl. 99444) Thisinvention relates to a liner for oven racks.

One of the objetcs of this invention is to provide a liner which isadapted to be positioned on the wire rack of an oven for the purpose ofprotecting the wire rack from greases and/or other drippings which arenormally deposited on the rack.

Another object of this invention is to provide a liner which is providedwith means for catching the drippings and preventing same fromspattering or otherwise soiling the interior of the oven. With thisinvention the liner is positioned on the conventional oven rack so thatthe food product to be baked or cooked is placed on the liner, and anydrippings from the food product will be deposited on the liner insteadof on the wire rack so that upon removal of the liner the rack and theinterior of the oven will be clean. This eliminates the cleaning ofdeposited drippings from the food product which normally adheres to theinterior of the oven.

Another object of this invention is to provide a liner or pan of theforegoing characteristics which has means for retaining its position onthe rack and is also provided with means for the passage of air to allowthe air currents to circulate in and around through the liner.

Another object of this invention is to provide a structure of theforegoing character in which all the grease and other drippings areretained on the liner and in which the liner is formed of an aluminumfoil of a gauge sufficient to maintain the required strength but whichis made inexpensively so that it may be disposed of after a single use.It may, however, also be repeatedly reused.

Other objects will become apparent as this description progresses.

In the drawings:

FIG. 1 is a view of an oven with the liner forming this inventiondisposed therein.

FIG. 2 is a top view of the liner.

FIG. 3 is a view taken on lines 33 of FIG. 2, and

FIG. 4 is an enlarged sectional view taken on lines 4-4 of FIG. 1.

The liner, designated generally by the numeral 10, is adapted to besupported on a wire frame rack, generally indicated at 12, supported inthe interior of the oven 14. The wire rack 12 is the conventionalstructure found in ovens in which the rack has the usual wire borderedmember 16 with spaced wires 18 extending therebetween. The spaced wires18 extend parallel with the sides of the oven, that is, the spaced wiremembers 18 extend transversely of the length of the oven and run fromfront to back. The wire rack is supported in a conventional manner inthe oven and is removable. Normally a plurality of such wire racks aresupported in an oven.

The liner is of rectangular shape and is formed of a metallic foilrolled from metal having good heat re flecting surfaces and which can beproduced at a low cost per unit to permit it to be disposable. Analuminum foil of a thickness of .004 is well suited for this purpose.

The liner 10 has a border edge 20 which is rolled as at 22 to provide acontinuous border for supplying a degree of rigidity to the liner.

The liner has a plurality of spaced parallel longitudinally extendingraised line members or ridges 24 which coincide with the wire members18. These raised members or ridges 24, as best seeen in FIG. 4, extendupwardly of the normal top plane of the liner surface. The wall surfacesbetween the ridges 24 are curved downwardly or concaved to provide aplurality of longitudinally extending troughs 26. Each trough 26 extendsbetween two adjacent ridges 24. This is likewise true of the surfaceareas between the longitudinal border edge 20 and the adjacent ridges24, thereby providing a trough 28 adjacent each of the longitudinalborders, which are similar to troughs 26. A continuous ledge 29' extendsbetween the troughs and the border edge 22. The liner is provided withspaced openings 29 positioned in the troughs 26, each bounded by anupwardly extending flange 30. The openings are staggered.

The liner is positioned on the wire rack 16 so that the raised linemembers or ridges 24 fit over and sit on the spaced wire members 18 andare engaged by them to firmly position and retain the liner on the rackagainst displacement when something is positioned on the liner and onthe rack.

The spaced openings 29 permit the heat to circulate through the liner inthe oven and the shallow troughs 26 and 28 will serve as pockets toretain any of the grease, oil, drippings, etc., from the baked productplaced thereon. The flanges 30 will prevent the grease from flowing outthrough the openings 29. The shallow troughs will each retain suchgreases which might be deposited therein and will prevent its passagesto the adjacent rows or troughs and prevent it from all settling in onerow or trough. This keeps the drippings distributed on the liner. Theborder edge 20 will prevent the drippings from flowing off the liner.

The liner is readily removable from the wire rack merely by lifting ittherefrom. The liner may be removed and cleaned and reused, or it may bedisposed of and a new liner may be substituted as the cost per liner isextremely low.

It will be understood that various changes and modifications may be madefrom the foregoing without departing from the spirit and scope of theappended claims.

What is claimed is:

1. A removable liner for oven racks which has spaced cross-members, saidliner comprising a member having a plurality of spaced parallelcontinuous extending ridges and spaced parallel continuous extendingtroughs with said troughs extending between said ridges and soconstructed that when said liner is positioned on the oven rack thespaced parallel extending ridges will register with and rest on thespaced cross-members to cover said crossmembers and the troughs willextend between and below said cross-members, and a border surroundingsaid liner and formed integrally therewith, the bottom edge of saidborder lying substantially on a horizontal plane defined by the top ofsaid ridges.

2. A structure defined in claim 1 in which openings are provided in thetroughs permitting the air to circulate through the liner and in whichthe liner is made of aluminum foil.

3 4 3. A structure defined in claim 2 in which the openings 2,466,8594/49 Northup 12639 are provided with adjacent flanged surfaces.2,884,849 5/59 Priem 99-444 4. A structure defined in claim 1 in whichthe liner is 3,113,505 12/63 Keppler 12639 made of aluminum foil andopenings are provided in the troughs and in which the border is rolled.5 FOREIGN PATENTS 4 ,9 6 3 References Cited by the Examiner 67 7 6/ 7Great Bntam UNITED STATES PATENTS FREDERICK L.
